Abstract:
Objective:To explore the clinical efficacy of treating external iliac artery dissection in renal transplantation by artificial vascular replacement.Methods:Four sudden intraoperative cases of external iliac artery dissection were selected.After removing vascular sutures, intimal arterial peeling blocked external iliac artery( n=3)and transplanted renal artery( n=1). Artificial vascular replacement of external iliac artery was performed using artificial vessels made from puffed polytetrafluoride ethylene(ePTFE). Secondary perfusion was performed in four transplanted kidneys for anastomosing with internal iliac artery. Results:One patient regained normal renal function within 1 week post-operation.Two cases had delayed graft function.Another case had delayed graft function plus acute rejection.After hemodialysis, renal function normalized at 2-3 weeks post-operation.During a follow-up period of(0.5-5.0)years, transplanted kidney function remained stable, blood supply, skin temperature and movement of operated lower extremities normalized.Conclusions:The incidence of vascular dissection of external iliac artery is not high during renal transplantation.However, the disease has a rapid and dangerous progression.The consequences of delayed intervention are quite serious.Treating external iliac artery dissection with renal transplantation may achieve satisfactory clinical outcomes.
